. Application July 11, 1938, Serial No. 218,707

' 3 Claims. (on. 72-13 This invention relates to storage tanks for liquids, such as oil, water and the like, and its general object is to provide a tank that combines the use of concrete and wood in its construction, in that it is made up of reinforced slabs or blocks 1-. of concrete, with strips of wood between the same,

the strips allowing for free expansion and contraction of the concrete slabs, without cracking, damaging or displacement thereof, thus eliminating those disadvantageous features which are inherent in tanks of this character composed entirely of concrete, and my tank has all of the advantages of a concrete tank over a metal tank, due to its rust-proof non-corrosive qualities and ability to resist erosion and deteriorating agents.

A further object is to provide a tank that includes separable parts which can be readily assembled to erect a tank of any height, and the wooden strips not only allow for expansion and contraction, but provide a leakproof joint, as will be apparent.

Another object is to provide a tank of the character set forth, that is simple in construction, easy to erect, and extremely eflicient in use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims. 1 f

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding I parts throughout the several views, and in which:

Figure l is a view of a tank constructed in accordance with the present invention.

Figure 2 is a transverse sectional view taken therethrough. Figure 3 is a fragmentary vertical sectional view. I

Figure 4 is a vertical sectional view taken through a tank, with a concrete top cover supported by uprights. v

Referring to the drawing in detail, it will be inclusive, a tank which includes superimposed cylindrical wall sections, so that it will be obvious that tanks constructed in accordance with the 55 forth in the objects of the invention.

noted that I have illustrated in Figures 1 to 3,

Regardless of whether or not the tank includes one or more sections, it is provided with a concretebase I that is shown as being of circular formation, beveled outwardly from its upper edge, and mounted on the base is a circular bottom wall 5 or floor 2 that is of lessdiameter than the base.

The bottom wall or floor is made up of blocks 3 of concrete reinforced by any well known means, with strips 4 of wood between the same and an annular rim or band 5 surrounding the 10 blocks and strips and which is composed of arcuate strips 6 of wood arranged in end-to end relation. The blocks and strips are disposed in fitting association with each other, and may be secured together by suitable binding material. 15

The cylindrical Wall of, the tank or each cylindrical wall section, as the case may be, is made up of elongated arcuate or transversely curved slabs I of reinforced concrete, having wooden strips or inserts 8 of cross sectional frusto-coni- 2 cal formation between the same and engaged therewith. Secured to the upper ends of the slabs I and strips 8, is a circular dividing member.

1 9 composed of. arcuate strips I!) of wood. The

wall section is of a diameter to fit about the outer 25 circumference of the band 5, as shown, and a dividing member 9 is provided between each wall section.

Hoops or bands I I are employed for holding the slabs 1 and strips 8 together in binding engage- 3 ment, and the holding means as shown are of the rod type having their ends secured together by turn buckles l2.

A roof or top cover 13' may be provided for the I tank, and as shown in Figure 1 is of conical 35 formation, but is made from reinforced concrete. Brace rods M are also provided when the tank is constructed to a height to require the same,

extend through the roof [3 and are secured thereto by nuts, in the'form as shown in Figure 1.

A flat top cover l6 of reinforced concrete may be provided, as shown in Figure 4 and it may be supported by columns or uprights ll, but

in any event-it rests upon a wooden dividing member 9. a

It will be obvious that any suitable inlet and outlet means having valves or the like of any type may be employed for use with the tank, and a ladder or the like, together with suitable openings in the wall or top cover to allow ingress and egress, may be provided, as will be apparent.

It is thought from the foregoing description 5 that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is: g

l. A storage tank comprising a base, a bottom wall seated on said base and including concrete blocks, strips of wood between the blocks, an annular rim surrounding the strips and blocks and composed of arcuate strips of wood arranged in end to end engagement, a cylindrical wall seated upon the base in surrounding engagement with said rim and including arcuateshaped reinforced concrete slabs, cross sectional frustoconical strips of wood between and engaged with the slabs, and said strips of wood providing expansion and leak proof joints between the blocks and slabs.

2. A storage tank comprising a concrete base, a bottom wall seated on said base and being of a diameter to be spaced from the outer edges thereof, said bottom wall including blocks of re inforced concrete, strips of wood between'the blocks, an annular rim surrounding the blocks and strips and made up of arcuate shaped strips of wood having their ends disposed in engagement with each other, cylindrical wall sections disposed in superimposed relation with respect to each other, the lowermost wall section being seated on said base in surrounding engagement with said rim each wall section including slabs of reinforced concrete, strips of wood between the slabs, an annular dividing member between the wall sections and composed of arcuate strips of wood, all of said strips of wood providing expansion joints between the blocks and slabs, hoops surrounding the cylindrical wall for holding the slabs and strips thereof in binding engagement with each other, a conical top cover 1 for the tank, and brace rods between the top cover and the base.

3. -A storage tank comprising a base, a cylindricalwall seated upon the base and made up of
